ATTORNEY@ UNITED STATES Pivllzlfrr OFFICE- MICHAEL MACHROL, 0F KENOSHA, WISCONSIN.

To, all whom t may concern:

Be it known that I, MIcHAEnMACHRoL, la citizen of the United States,` and a resident of the city of KenoshaJ in the cou-.nty of Kenosha and State of Wisconsin, have invented a mewand useful Improvement in Flywheel-Balancers, of which the'following is a full, clear, and exact description.

4Mylinvention relates to improvementsin -Hy wheel balancers, and it consists in the combinations, constructions and arrangements'herein described and claimed.

A further object of my invention is to pro-4 vide a balancing device which may be ad justed to fly wheels of different sizes.'

Other objects and advantages will appear in the followingspecification,and the novel.

features of the lnvention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompan ng drawin forming part of this l1 igqihap ication, in w lgure 1 is 'a central sectional viewl through the device,

Fig. 2 is a plan view, and Fig. 3 isa section along -the line 3-3 of Fig. 2. n carryingv out my invention I provide a` base lof any suitable shape. 'Io this base is secured a fulcrum post 2 of the shape shown in the drawings. The latter has a conical recess 3 at its top. A curved arm 4 is secured at 5 to the base plate, and extends above the center of the fulcrum post 2.

The Hy lwheel 6 is supported on a block 7 having a conical recess 8 on its under side arranged to receive the fulcrum post 2. This block is provided with one or more shoulders 9, so that Hy wheels of different sizes ma be supported and balanced. The centra portion ,10 of the plug 7 extends through the shaft opening in the Hy wheel, as shown vin Fig. 1. The portion -10 has a threadedv opening 11, in which is secured a threaded portion 12 of al rod 13,'whose lower end Specification of Letters Patent.

is pointed and which rests `in the recess at the top of the post 2, thus suspendmg the Hy wheel., Theupper end of theJ rod 13 is bored to receive an adjustable p ointer 14 which may be retained in positlon by a set screw 15. A scale 16 is carried by an arm 17, which is adjustably secured to they arm 4 by means of a set screw 18, o1'- in any other.l similar manner.'

Mounted 1n a slot 19 of the base 1 is a l Patented sept. 14,1c2o. Application led September 2, 1919.y Serial No.321,056. n

slidable block 20, having ascrew 21 provided with a supporting head 22.'

From the foregoing description of the various parts of the device, the 4operation thereof. may be readily understood. The Hy wheel is placed on the block 7, and the pointer 14 is ad'usted lso as to register with the scale 16. I the heavier part of the Hy wheel should swing the poi-nter away from the scale, then the Hy wheel is turneduntil the pointer swings to a maximum distance to the rightin Fig. 1. The scale is provided -with marks 23, which indicate the amount of material to be removed from the heavy side of the fly wheel. This may be in pounds, ounces, or any suitable measure. The heavy side of the fly wheel is marked with chalk or any similar material, and thus the wheel is turnedso as to bring the heavier 4side above the supporting member 22, the

screw being turned to support the under side of the -fly wheel. drilled while being supported by the head 22, and the surplus material removed.

With the device described above, the op- I eration of locating the heavier. portion ofthe Hy wheel and of removing the excess portions is greatly facilitated and is rendered very accurate.

y adjusting the scale 23 and the pointer 14, the device may be used to balance Hy wheels of different sizes.

I claim:

1. In a Hy wheel balancing device, a base, a fulcrum post carried thereby, a fly wheel support having a portion arranged to enter The latter may now be the shaftopening of the center of the Hy wheel, said support havingl a portion arranged to engage and be supported byv said fulcru-m post, a slidably adjustable pointer carried by said Hy wheel support, and a scale coperating with said pointer for indicating the excess weight on one side of the Hy wheel, and 'being adjustable toward landf away from said pointer.

2. A Hy wheel balancing device "compriS- ing a base, a fulcrum post carried thereby and having a conical shaped recess at` the top, a ily wheel supporting block having a recess arranged t0 receive the upper portion of the fulcrum post, a rod secured to said fly wheel support, the lower end of the rod being pointed and being arranged to rest on the conical shaped recess in said f-ulcrum post, and an adjustable pointer carried by sald rod.

' 3. A iy wheel balancing device comprising a base, a fulcrum post carried thereby and having a conical shaped recess at the top, a fly wheel supporting block having a recess arranged to receive the upper portlon of the fulcrum post, a rod secured to said fly wheel support, the lower end of the rod being pointed and being arranged to rest on the conical shaped recess in said fulcrumv post, an adjustable pointer carried by said rod, and an adjustablesupporting head carried by `the base, rand arranged to .engage the under side of the fly whee to permit t e drilling'of the latter.

4, A fly wheel balancing device comprising a base, a ful'crum post carried thereby and having a conical shaped recess at the top, a fly Wheel supporting block having a recess arranged to receive the upper portlon of the fulcrum post, a rod secured to said fly wheel support, the lower end of the rod being pointed andbeing arranged to rest on the conical shaped recess in said fulcrum ost, a slidably adjustable` pointer carried y said rod, an arc shaped scale support carried by said base and arranged to extend above said pointer and an adjusf'able 'scale carried by said scale support and-movable toward and away from said ointer. y
